Beschreibung
Zusammenfassung:	The invention discloses an anti-tarnishing UV varnish and a preparation method of the anti-tarnishing UV varnish. The anti-tarnishing UV varnish is obtained by improving the formulation of the traditional UV varnish. UV offset ultramarine is added into the UV varnish to offset the effect of yellow substances in UV varnish on printing to make the UV varnish not become yellow after long time using. The addition amount of UV offset ultramarine accounts for 8%-15% of the UV varnish by weight. As the UV offset ultramarine is non-toxic, environmentally friendly, and does not affect the foods and other substances in the packaging, the said anti-tarnishing UV varnish can be used for the printing of food packages and meets the monitoring requirements of the country on product quality safety.
